SHADE-ROLLER.

Specification of Letters Patent.

Patented Apr. 21, 1914.

To all whom it may concern Be it known that I, EDMUND F. I-IARTs- HORN,a citizen of the United States,residing in Newark, county of Essex,State of New Jersey, have invented a new and useful Shade-Roller.

The object I have in view is the production of a shade roller for heavywork.

This invention relates particularly to shade rollers for use uponawnings, large curtains, and similar structures. I-Ieretofore, suchrollers h ave been reinforced by a solid round reinforcement. When theroller is as much as four inches in diameter, the reinforcement must bemade of a large and expensive piece of wood. According to my invention,I utilize relatively cheap material and produce a roller possessinggreat rigidity and strength, at the same time being light in weight.Another objection to a roller made of a single piece of wood, is thatseasoned material must be employed, otherwise the roller will warp. Evenwhen the material is carefully selected, in use,particularly for awningsoutside of buildings, the roller is apt to warp and thus lose its shape.

These and further objects will more fully appear from the followingspecification and accompanying drawings, considered together orseparately.

In the drawings, Figure 1 is a longitudinal sectional view of a rollerembodying my invention. Fig. 2 is a section on the line 2-2 of Fig. 1.Figs. 3, 4, 5 and 6 are sectional views of modifications.

In all of the views, like parts are designated by the same referencecharacters.

The preferred roller comprises a shell 1. This shell is made of sheetmetal, preferably tin. It is the full length of the roller; that is tosay,-it extends from end to end of the roller. Preferably it is made ofa single piece, rolled to shape, with a lapped joint, as shown in Figs.2, 3, 4 and 5. The method of joining it, however, is immaterial. Alarge, long roller formed of tin would lack the necessary rigidity,consequently, I insert within the shell a reinforcing core 2. This corepreferably extends from one end of the roller to a position close to theother end, the space between the core and the other end of the rollerbeing occupied by the spindle 4 and spring 5. In Fig. 1, the usual spear3, spindle 4, and spring 5 are shown. On the other end of the roller isthe usual end pin 6. This pin is shown as attached to a plate 7, andthis plate is secured by screws 8 to the reinforcing core 2. This formsa very cheap fitting for this end of the roller.

The core is provided with a bearing 9, for the end of the spindle. Thepreferred form of core is shown in Fig. 2. This comprises a centermember 10. This member may be satisfactorily made of wood. A piece ofboard, of commercial thickness, may be employed. The edges are roundedto shape, so as to snugly fit within the shell. Wing members 11, 11, aresecured on each side of the center member. Suitable fastenings 12, suchas nails, secure the parts together. The edges of the wing members arerounded so as to make a close fit with the shell. This structure is verysimple and cheap of manufacture; and it is much lighter than a solidwooden roller. Being formed of cheap stufi, it can be built with aminimum of cost. A great advantage lies in the fact that the wingmembers, when they warp, will be counteracted by the center member, andthe center member, when it warps, will be counteracted by the wingmembers.

Instead of the fastenings 12, the wing members may be provided with ribs13, shown in' Fig. 3. The parts may be further secured together by glue.

The arrangement shown in Fig. 4 cmbodies four strips, 14, suitablysecured together by fastenings, such as nails.

Instead of employing a wooden core, a metal core, 15, shown in Fig. 5,may be employed. The core preferably extends from the pin of the rollerto the spear, and is preferably made in a single piece, as shown. It maybe made, in a number of sections, however, suitably disposed within theshell so as to strengthen the latter and prevent it from'collapsing.This is shown in'Fig. 6.

In accordance with the provisions of the patent statutes, I havedescribed the principle of my invention, together with the apparatuswhich I now consider to represent the best embodiment thereof; but Idesire to have it understood that the apparatus shown is merelyillustrative and that the invention can be carried out in other ways.

Having now described my invention, What I claim as new and desire tosecure by Letters Patent, is

l. A spring shade roller having a sheet metal shell of the length of theroller, a spindle Within the shell, a skeleton core extending throughthe greater part of the length of the shell, said core carrying abearing for the spindle.

2. A spring shade roller having a sheet metal shell of the length of theroller, a spindle having a bearing in one end of the shell, a reinforcedskeleton core extending 'from the spindle to the other end of the shell,said spindle having a bearing in the core. 7

.3. A spring shade roller having a sheet metal. shell of the length ofthe roller, a spindle having a bearing in one end of the shell, areinforcing skeleton core within the shell, said core being formed ofstrips of wood secured together in such a manner as to present numerouspoints of contact extending longitudinally of the shell, and a bearingfor the spindle in the core.

4. A spring shade roller having a sheet metal shell of the length of theroller, a spindle Within the shell, a core contacting with the shell atdiametrical intervals, the points of contact extending longitudinally ofthe shell, said core carrying a bearing for the spindle.

This specification signed and witnessed this 20th day of June, 1912.
